liquidio_init(9)

💖 liquidio_init(9) 💖

okay so real talk, this whole page lives in the Kernel API Manual (that's the manual name, bestie, it's not a section number situation, it's a whole vibe) and it's about one single function: liquidio_init. no cap. that's the whole page. slay.

---

✨ NAME ✨

liquidio_init — the entry point for the liquidio module 🎀

like, literally the front door. the main character. everything else in this driver is guest-starring.

---

🌸 SYNOPSIS 🌸

int liquidio_init (void );

that's it. that's the whole call. it hands you back an int, and honestly we love a return value that tells you how it went.

---

🦋 ARGUMENTS 🦋

• void — no arguments, bestie. zero. nada. it takes nothing, it needs nothing, it simply exists. icon behaviour.

---

👑 SEE ALSO 👑

okay this is the part where I hold your hand and walk you through the entire friend group, because this module is not an only child. every single one of these is a real one. iykyk 💅

and first up, the source file itself:

• the kernel file ./drivers/net/ethernet/cavium/liquidio/lio_main.c — go read it, it's giving source of truth

that's the whole group chat. every name matters, don't skip a single one. also note the liquidio_exit(9) at the end — yes, there's an exit to match the init, the symmetry is chef's kiss 🔥

ngl if you need the actual behaviour details of any of these, go read their pages — this one only claims that they're related, and I'm not out here inventing lore 🙈
